While the burden of COVID-19 in Rhode Island has diminished since 2020, Rhode Islanders' health continues to be severely impacted. We compared COVID-19 hospitalization rates among Rhode Islanders who did and did not receive the latest COVID-19 vaccination for the 2022-2023 and 2023-2024 COVID-19 seasons (November through March). Crude and age-adjusted rate ratios were calculated for each season comparing hospitalization rates of unvaccinated and vaccinated individuals. During the 2022-2023 season, individuals who were not vaccinated with the bivalent COVID-19 vaccine were 3.6 times (95% CI=2.8-4.6) more likely to be hospitalized for COVID-19 than individuals who received the vaccine, whereas during the 2023-2024 season, not receiving the updated vaccine was associated with a 2.4 times (95% CI=1.8-3.3) higher risk of hospitalization. The study provides the first assessment of the protection from hospitalization provided by COVID-19 vaccinations among Rhode Islanders and highlights the importance of continued vaccination for COVID-19.
